摘要： A metering roll, employed between the developing station and the transfer station of a photocopier which uses a liquid toner, controls the thickness of the liquid on the photosensitive drum surface when it is presented to the transfer station. Elements fixed between the drum and roll maintain the central metering portion in a substantially constant spaced apart relationship to the photosensitive drum surface and thereby tend to limit and control the thickness of developer on the drum surface at the transfer station. The elements have different surfaces in sliding, frictional contact with the drum and roll respectively. In one embodiment the elements are strips with opposite parallel surfaces, one in contact with the drum and the other in contact with the roll. In another, the ends of the strip are mounted on reels so that the strip may be moved to vary wear points on the strip if any appear.

摘要： A jam detector circuit for use in a photocopier employs feedback and visual indication circuitry for providing a stable and easily adjusted detector. Feedback is provided to desensitize the circuit to sensing device operating parameters which vary according to and within manufacturing specifications. The visual indication circuitry allows a predetermined range of signal change to be defined thereby enabling easy "set-up" of the circuit without the need of electrical metering apparatus.

摘要： A sheet stripping apparatus and method used in a photocopying machine employ a resiliently biased sheet stripping element in contact with the photosensitive surface of the copier for detaching a leading edge of a copy sheet as it moves toward the sheet stripping assembly. A moving deflection surface, such as a knurled roller, is positioned immediately adjacent the operative portion of the sheet stripping element for deflecting the detached leading edge of the copy sheet away from the sheet stripping element and toward an exit path. A friction roller in juxtaposition to the deflection surface provides a nip for grabbing the copy sheet and directing it along the exit path. The friction roller is preferably driven at a velocity greater than the velocity of the photosensitive surface.

摘要： A curved blade overlays the marginal portion of a photocopier drum photosensitive surface at the transfer station to engage copy sheets and direct them to a transport assembly removing the sheets from the transfer station. The blade is pivotally mounted at one end and connected to a reciprocating actuator at the other end. It is pivoted away from its overlaying position, after the transport assembly engages the leading corner of the sheet so that the sheet can then contact the marginal portion, and back to its overlaying position after the trailing edge of the sheet has left the surface of the drum. In one embodiment the actuator is mechanically responsive to the photocopier scanner. In another embodiment, the blade is pivotable about an intermediate portion, and the actuator is operated by a solenoid energizable by a switch at the appropriate times.
摘要翻译：弯曲的刀片覆盖在转印站处的复印机感光表面的边缘部分以接合复印纸，并将其引导到从转印站移除纸张的运输组件。叶片在一端可枢转地安装并且在另一端连接到往复式致动器。在运输组件接合片材的前角之后，其枢转远离其重叠位置，使得片材然后可以接触边缘部分，并且在片材的后缘已经离开片材的表面之后返回到其重叠位置鼓。在一个实施例中，致动器机械地响应于复印机扫描器。在另一个实施例中，叶片围绕中间部分可枢转，并且致动器由适当时间由开关激励的螺线管操作。
